SECTIONAL BOOKCASE 0R LIKE ARTICLE OF FURNITURE HAVING PARTS SLIDING IN AND OUT THEREIN- SPECIFICATION forming part of Letters Patent No. 762,071, dated June '7, 1904.

Application filed September 29, 1902. Serial No. 125,268. (No model.)

To all whom it may concern.-

Be it known that I, HUGH (J. LORD, a citizen of the United States, residing at Erie, in the county of Erie, State of Pennsylvania, have invented certain new and useful Improvements in Sectional Bookcases or Like Articles of Furniture Having Parts Slidingin and out Therein, of which thefollowingis a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to sectional bookcases and like articles of furniture having parts sliding in and out therein; and it consists of certain improvements in the construction thereof, as will be hereinafter fully described, andpointed out in the claims.

The invention is peculiarly adapted to sectional bookcases having doors arranged to slide back under the tops of the sections. and the invention, as illustrated, is applied to such a section.

In the drawings, Figure 1 showsafront elevation, partly in section, of the section; Fig. 2, a sectional fragment showing the hinge for a portion of the paralleling device; Fig. 3, an enlarged perspective view of the doorhinge; Fig. 4:, a perspective view of the paralleling mechanism; Fig. 5, a section on the J .line 5 5 of Fig. 1.

A marks the bottom of the section, which is preferably of the ordinary two-part construction, B B the sides of the section, and O the top, the top being preferably arranged to enter between the bottom pieces of a superimposed section, as commonly.

1) marks the door. The door is hinged on the pintle E, the pintle being preferably provided with a roller 0. The hinge (Z is formed of the plate (Z,havinga perforation d through which a screw is passed into the door. One side of the plate is bent up, forming the lug cl", which abuts against the roller 6, forming a support for the door.

Extending from the opposite side of the plate d is a lug d having a perforation preferably concentric with the pintle E when the door is in its closed position. The door is to be lifted as commonly in this class of cases and slides back between the ends B B, the

door riding on the roller 0. The top piece C is provided with two grooves 0 c, and arranged in these grooves are the paralleling rods F F. These rods are preferably formed by bending sheet-metal strips into the form of tubes. At the ends of the tubes so formed the strips are extended and bent down, forming arms f f. The lower ends of the arms are connected with a supporting-link I at the points a j, and the link I is hinged at z" in the perforation of the lug cl". The rods F are supported in the grooves by the staples G, which are driven into the end of the top (1, the lower end 9 of the staple extending into the end of the tubular rod F. The staple has a shoulder g.

A spring H is arranged on the portion 5 of the staple, one end of the spring extending through the tube, and thus locking it with the tube, and the opposite end of the spring being tensioned against the shoulder g. The spring is tensioned to exert force on the arms ff in a rearward direction, so that when the door is raised to a horizontal plane the springs acting through arms ff and link I draw the door back.

It will be noted that as one end of the door is moved it acts through the link 1, arms f, and rods F upon the similar mechanism at the opposite side of the door, thus carrying the opposite side of the door in parallel relation with thatside or end initially moved. It will also be noted that it effects this action on the door when the endof the door is moved either in or out.

The distance between the rods F F, length of the arms ff, distance between the points a 1, and length of the link I should be so proportioned that the direction of travel of the point i" will be in substantially a straight line. This proportion may be readily ascertained by a few experiments. The relation of parts shown in Fig. 5 will accomplish approximately this result.

It will be noted that the rear end of the door as it moves backward is entirely supported by the linkI and armsf'f, so that all friction due to the weight of this end of the door is entirely obviated. noted that the linkand-arm construction prevents the upward movement of-the end of the It will also be IOO door as it is moving backward, due to the weight of the front end of the door in front of the pivot formed by the lug E.
